Considering the results of the 3.20 Cyber Attack, leaks of personal information by card companies, and so on, convenience and efficiency cannot be guaranteed without security as a prerequisite. In addition, it is more likely that customers' interests seem to be interfered with in financial institutions than in any other industry. Therefore, when a security accident occurs, users may suffer mental damage and monetary loss, leading to class action, customer defection, loss of reputation, and falloff in international credibility, which all may have a significant effect on the business continuity of corporations. This study integrates the representative information security certification systems in order to improve the efficiency of information security management and demonstrate the necessity of information security management system certification for the financial sector. If the certification is needed, we would like to recommend the desirable development direction.

Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.

A recent trend of global shipping industry adopting Port State Control (PSC) system is recognized as a proficient mechanism in preventing costal traffic accident and protecting marine environment. Disadvantages of Korean shipping companies in PSC inspection are unavoidable as Tokyo MOU imposed priority listed flag to Korea. Having stated above, appropriate research and prompt preparation in compliance with current PSC requirements for the Korean shipping companies have become an immediate need. The objectives of this study are : First, to review in understanding of PSC in overall and foundation of enforcement. Second. to study interaction of international treaties regarding PSC. Third, to compare practical compliance among the countries and to open up a case study on Korean shipping companies in adopting PSC. Last, to suggest direction to the Korean shipping companies the most proficient way in compliance with the current Tokyo MOU requirement. Korean flagged vessels have become prioritized target in PSC inspection as Tokyo MOU imposed priority listed flag to Korea due to high detention rate of its fleet. Disadvantage of a priority listed flag is a burden in its proficient fleet operation. This study suggests solutions to the disadvantages as below. : 1) Change shore management system, and provide continuous & quality education to crew members 2) Form a network in sharing PSC information among the Korean shipping companies 3) Form a centralized function in which government, Korean Shipping register and shipowners can treat problems in a prompt manner.

This paper compared historical energy use from 2000 between Japan and Korea and reviewed literature of mid-and long-term low carbon energy scenarios and plans in both countries released since 2000. In terms of energy use pattern, there are similarities between Korea and Japan; high dependence on energy imports, high proportion of manufacturing industry among OECD countries, closed electricity system disconnected with foreign countries, and high proportion of nuclear power generation with low proportion of renewable electricity despite of high potential of renewable energy. Differences are as follows; decreasing trend in Japan and increasing trend in Korea in terms of energy demand and supply, difficulty of exchanging electricity between regions in Japan unlike Korea, and prospect of nuclear power, that is, curtailing in Japan while expanding in Korea according to governmental plan. Energy Basic Plan in both countries established before nuclear accident in Fukushima required expanding about two times of nuclear energy by 2030, while civil society's energy scenarios suggested reducing energy demand, phasing-out nuclear power, and expanding renewable energy. This paper will serve as a base for future studies about long-term energy scenarios and plan in Japan and Korea.

Aid to Navigation (AtoN) is the artificial facilities to facilitate the ship's safe navigation using light, shape, color, sound, and radio waves. IALA has developed and operated the educational course for expert groups for the design, deployment, and management of AtoN. Also, maritime educational institutes have operated various educational courses for safe navigation through the ship's operation and ECDIS curriculum for seafarers. However, education using the AtoN Simulator System is needed to prevent marine accidents caused by misunderstanding of the AtoN according to various topographical, environmental, and maritime traffic environments. In this study, the existing ship handling simulator and AtoN simulator were applied to develop educational modules for accurate understanding and application of AtoN in various environments, enhancing the quality of education from the existing theoretical point of view and improving practical use to maximize educational efforts.

Background: In comparison with other industries, the construction industry still has a higher rate of fatal injuries, and thus, there is a need to apply new and innovative approaches for preventing accidents and promoting safe conditions at construction sites. Methods: In this study, the effectiveness of a new incentive system-the surprising incentive system-was assessed. One year after the implementation of this new incentive system, behavioral changes of employees with respect to seven types of activities were observed. Results: The results of this study showed that there is a significant relationship between the new incentive system and the safety performance of frontline employees. The new incentive system had a greater positive impact in the first 6 months since its implementation. In the long term, however, safety performance experienced a gradual reduction. Based on previous studies, all activities selected in this study are important indicators of the safety conditions at workplaces. However, there is a need for a comprehensive and simple-to-apply tool for assessing frontline employees' safety performance. Shortening the intervals between incentives is more effective in promoting safety performance. Conclusion: The results of this study proved that the surprising incentive would improve the employees' safety performance just in the short term because the surprising value of the incentives dwindle over time. For this reason and to maintain the surprising value of the incentive system, the amount and types of incentives need to be evaluated and modified annually or biannually.

Flow accelerated corrosion(FAC) of the carbon steel piping in pressurized water reactors(PWRs) has been major issue in nuclear industry. Severe accident at Surry Unit 2 in 1986 initiated the worldwide interest in this area. Major parameters influencing FAC are material composition, microstructure, water chemistry, and hydrodynamics. Qualitative behaviors of FAC have been well understood but quantitative data about FAC have not been published for proprietary reason. In order to minimize the FAC in PWRs, the optimal method is to control water chemistry factors. Chemistry factors influencing FAC such as pH, corrosion potential, and hydrazine contents were reviewed in this paper. FAC rate decreased with pH up to 10 because magnetite solubility decreased with pH. Corrosion potential is generally controlled dissolved oxygen (DO) and hydrazine in secondary water. DO increased corrosion potential. FAC rate decreased with DO by stabilizing magnetite at low DO concentration or by formation of hematite at high DO concentration. Even though hydrazine is generally used to remove DO, hydrazine itself thermally decomposed to ammonia, nitrogen, and hydrogen raising pH. Hydrazine could react with iron and increased FAC rate. Effect of hydrazine on FAC is rather complex and should be careful in FAC analysis. FAC could be managed by adequate combination of pH, corrosion potential, and hydrazine.
